[S-CG41] Hard-Rock Drilling Science: From Continental to Deep Sea Drilling, and Oman Project

Sun. Jun 6, 2021 10:45 AM - 12:15 PM Ch.19 (Zoom Room 19)

convener:Eiichi TAKAZAWA(Department of Geology, Faculty of Science, Niigata University), Katsuyoshi Michibayashi(Department of Earth and Planetary Sciences, Nagoya University), Keishi Okazaki(Japan Agency for Marine-Earth Science and Technology), Chairperson:Katsuyoshi Michibayashi(Department of Earth and Planetary Sciences, Nagoya University), Eiichi TAKAZAWA(Department of Geology, Faculty of Science, Niigata University)

The IODP and ICDP have decided to launch a new international science framework, and hard rock drilling science is about to enter the preparatory period for the next phase. Therefore, drilling proposals from a new perspective and the production of scientific results based on existing drilling projects are expected. In this session, we invite presentations on the scientific results of hard-rock drilling. We also invite related studies of on-land geological investigations of Oman ophiolites and experimental studies. The session is intended to be interdisciplinary, including the fields of geophysics, geochemistry, petrology, engineering, and biology. This session is co-hosted with the focus group of hard rock drilling science.
